"I recognize that she's a beautiful girl, but we have this brother-sister relationship," Lowe said. "You don't understand - we're talking about her bodily functions! I just don't look at her that way."

Lowe also revealed that his family have been incredibly supportive of his and Murgatroyd's bid to win Dancing with the Stars' Mirrorball Trophy.

"They absolutely love it. And they're all so supportive," he declared. "It doesn't matter how bad I mess up the dance, once it's over, they're like, 'You should've gotten a 10! You were robbed by Bruno, Len and the whole gang!'"

Lowe and Murgatroyd will be back in the ballroom tonight (April 15) for the Side-By-Side Challenge, where they will dance alongside another couple.
